events : an event is a
(time, path, type) tuple,
where type∈{ new, delete } ;
− both new files and file updates are represented by new
events ;
− the RECENT files (RECENT-*.json) contain
the event stream ;
− the updates of RECENT files are not represented in
the event stream.

→ discarded : new events where file path
does not exist in the remote archive.

files fetched : files fetched in full syncs are not included

→ new files : a fetched file is a new file if
it doesn't exist yet in the local archive.

links fetched : counts new events where fetching
path results in a symlink.

dud deletes : counts delete events where file
path does not exist.

time sync errors : time spent waiting for (loop & full) syncs
that ended in error.

sync in/out : bandwidth based on --stats ; lowerbound ;
full syncs are not included.

bandwidth files : based on files fetched ;
b/s == bits per second ;
upperbound because rsync compression (option -z) is not taken
into account.
